HES FT-1 Momentary Foot Switch SPDT
The HES FT-1 is a momentary foot switch designed for hands-free activation in access control and security applications where door release or gate control must be triggered without manual button press. The SPDT (Single Pole Double Throw) switching pattern delivers reliable momentary contact closure — ideal for timed electric strike activation, emergency exit scenarios, and integrated access systems where operational continuity and consistent switching behavior matter.
Key Features
- SPDT Momentary Contact: Single Pole Double Throw configuration with momentary (non-latching) closure. Prevents accidental sustained activation and integrates cleanly into normally-open or normally-closed control circuits.
- Foot-Operated Design: Hands-free activation eliminates need for manual buttons. Critical in emergency egress, medical facilities, and food-service environments where personnel cannot release hands.
- Industrial-Grade Construction: Built for high-traffic security environments. Rated for repeated cycling without performance drift or contact wear-out.
- Standard Enclosure Mount: Compatible with common access control and security system enclosures. No custom brackets or special installation hardware required.
- Direct HES Integration: Works seamlessly with HES electric strikes, magnetic locks, and door release hardware. No intermediary relays or signal conditioning needed.
- US Manufactured: Sourced and built domestically, ensuring rapid availability and consistent quality control.
The momentary contact design is the operational core of the FT-1. Unlike maintained switches that hold a circuit as long as the pedal is pressed, momentary closure fires a brief pulse to the strike controller. This prevents common failure modes — accidental prolonged door unlock, power waste on heater elements, and unintended gate cycling. A typical installation pairs the FT-1 with a 12VDC or 24VDC electric strike and a small delay timer (often built into the strike or an external relay module) to set dwell time (typically 0.5–3 seconds). The operator steps the pedal, the strike energizes for the set duration, and the door returns to locked state.
Deployment context matters here. In emergency exit scenarios (hospital corridors, secure facilities), the FT-1 provides fast, intuitive egress without fumbling for a button or badge. In controlled-entry environments (loading docks, server rooms), hands-free operation is a hygiene and workflow win — personnel keep gloved or wet hands away from shared surfaces. In high-traffic secure vestibules, the foot switch reduces touch-point cross-contamination and accelerates throughput. The industrial construction means the switch tolerates boot traffic, spilled liquids (though it is not IP-rated for hose-down), and repeated jarring impacts in busy facilities.
Integration is straightforward. The SPDT terminals connect directly to a strike controller's input, or to a relay that drives the strike. No special power supply is required for the foot switch itself — it is a passive switching device. Wire gauge is not critical (18–22 AWG runs fine over 50+ feet), and the control voltage (typically 12V or 24VDC) is determined by the strike system, not the switch. If you are retrofitting an existing access control panel or replacing a worn momentary button, the FT-1 drops in as a direct mechanical substitute. Mounting is via adhesive backing or small through-holes into a floor box or enclosure edge — no demolition required.
The HES FT-1 is US-manufactured and carries no special certifications (it is a mechanical passive device), but it is well-suited to HIPAA-compliant environments and facilities requiring domestic-source documentation for procurement. Pair it with a HES strike controller or any third-party access control system that accepts 12V or 24VDC momentary contact input. For high-cycle sites (10,000+ activations per year), the industrial contact rating ensures minimal replacement frequency — typical lifespan is 5–10 years under normal use.

We've installed hundreds of HES electric strikes in hospitals, secure facilities, and high-security government sites, and the FT-1 foot switch is the most reliable hands-free activation device we've encountered for that ecosystem. What sets it apart is not exotic electronics — there are none — but rather the durability of the contact mechanism and the simplicity of the SPDT wiring. In a busy hospital corridor where a foot switch might be pressed 500+ times per day, cheap momentary switches fail within 6–12 months due to contact pitting and spring fatigue. The FT-1's industrial-grade contacts remain clean and responsive for years. We've also found that the SPDT pattern (as opposed to SPST) is underestimated — it lets you wire one switch into either a normally-open OR normally-closed logic without changing the switch itself, which is a lifesaver on retrofit jobs where the control circuit polarity is ambiguous. The main trade-off is that the FT-1 does not offer any feedback — no LED indicator, no solenoid confirmation — so you rely on the strike's own audible or visual feedback to know the activation worked. On noisy loading docks, that can be a minor UX gap, but it's the cost of simplicity and reliability.
Technical Highlights:
- SPDT Momentary Contact: Single Pole Double Throw means you have three terminals (common, normally-open, normally-closed). You can use the NO contact for normally-energized strikes, or the NC contact for fail-safe configurations. Momentary action ensures each foot press sends one pulse, no held current. This prevents heat buildup on the strike coil and eliminates the need for expensive power supplies rated for continuous duty.
- Industrial Contact Rating: Rated for high-cycle repetition (100,000+ cycles typical). Unlike consumer-grade switches that degrade after a few thousand presses, the FT-1's silver-alloy contacts withstand boot traffic and repeated use in security environments without functional drift.
- Passive Device: No batteries, no electronics, no microcontroller failure modes. The switch is purely mechanical — if it works when installed, it will work in 10 years assuming normal maintenance. This simplicity is a major advantage in facilities where MTBF and supply-chain risk matter.
- Standard 12V/24VDC Compatible: Works with any HES strike controller or third-party access system that can switch 12VDC or 24VDC momentary contact input. Wire runs to 50+ feet without signal degradation. No special cabling or conduit required beyond standard security-grade shielded pairs.
- US Manufactured: Sourced and assembled in the US. No overseas lead times, and domestic procurement documentation is straightforward for government and regulated-industry buyers.
Deployment Considerations:
- Foot switches must be mounted in high-traffic zones where they are visible and within natural foot reach (typically floor level or 2–4 inches above). Poor placement leads to operational friction — personnel revert to buzzing or manual buttons instead of using the foot switch, defeating the hands-free benefit.
- The FT-1 is not IP-rated and should not be exposed to standing water or hose-down cleaning. Install it in a recessed floor box with drainage if it will be near wet areas. Moisture on the contacts will eventually cause intermittent operation or failure.
- Verify strike controller dwell time (lock activation duration) is set correctly. A 0.5-second pulse is fine for most electric strikes, but some fail-safe locks require 2–3 seconds. Test the timing with the end-user before final sign-off to ensure the door unlocks reliably on every foot press.
- Wire the switch through a protective conduit or raceway in high-abuse environments. A loose wire run to a surface-mounted switch invites accidental pulls and tugs that can break the connection or damage the switch housing.
- If retrofitting into an existing strike circuit, use a multimeter to verify the polarity of the control voltage before connecting the FT-1. Reversing live and ground will not damage the switch, but the strike will not energize until you swap the wires.
The HES FT-1 is the right choice for integrators and facility managers who need a rock-solid, no-frills hands-free strike activation device. It's not smart — it has no analytics, no logging, no wireless — but that is its strength. In emergency egress, hygiene-critical environments, and facilities where simplicity and uptime trump feature lists, the FT-1 delivers exactly what you need, exactly when you need it.
