We originally designed this so a forklift operator would not have to get off and operate a machine. In that application we configure the relay as an "Impulse Relay". One press of the button and the relay contact #1 closes and relay contact #2 opens. Touch the button again and the relay operates the opposite way.
15 amp contacts on the relay can operate multiple relays or even a motor or a large light.
Unit operates at 120vac. Use for electric appliances, controlling illumination, heating, motors, ventilators, warning illuminating on the road, flashers, cyclers, frequently switched systems
