Product Description
LF40-01 air switch is provided with a snap action switching for higher current capacity, SPDT contact form and switch deadbands (also referred to as mechanical differential or hysteresis).
LF40-01 air switch can be used together with air button (also called as Actuator) for remote control purpose. It is widely used in garbage disposer, pumps for swimming pools and spas, hot tubs, sanitary equipment, out door machines, medical equipment etc. As a remote control switch, it is small enough to fix in the control box of the engine. Used as a remote control, the air switch has two actions:
1) Momentary action: when the air button is pushed, the air switch is actuated. When air button is released, the air switch will also be released. This is the way the basic pressure switches are working.
2) Alternate action (also referred to as latching or bistable): the first pushing on air button actuates the air switch, and the air switch keep actuating when air button is released. A second push on the air button will release the air switch.
