Double push-button, NC LF HPB22-D11

A double push-button switch combines two momentary contacts in one unit: one normally closed and one normally open. When the operator presses a button, a spring-loaded plunger moves inside the switch body, breaking the closed contact and making the open contact. Releasing the button reverses the action, returning the contacts to their resting state. This arrangement allows a single press to start one function while stopping another, which is essential for interlocks and emergency stops in professional catering equipment.

The switch is operated by pressing either the red or green button. The red button typically breaks the circuit, stopping the connected device, while the green button makes the circuit, starting it. The operator presses firmly until the internal click is felt, confirming the contact change. No setting or adjustment is required; the switch responds instantly to each press.

The unit is housed in a compact, sealed enclosure designed for front-panel mounting. The buttons are colour-coded red and green for immediate visual identification, reducing the risk of operator error in a busy kitchen environment.

This switch is used where a single action must control two opposing states, such as starting a motor while stopping a warning light, or engaging a safety circuit while disengaging a heating element. The normally closed and normally open contacts allow the same switch to manage both actions without additional relays.

Versions of this switch are available for different panel thicknesses and mounting hole sizes, ensuring compatibility with a wide range of catering equipment control panels.
