This is a HES JP1-2 D.P.D.T. momentary contact switch. It features a Double Pole, Double Throw configuration, meaning each of the two poles can be connected to one of two possible circuits. The momentary action ensures that the switch returns to its neutral position when the actuator is released.
This type of switch is ideal for applications requiring temporary circuit activation or selection, such as push-button controls, trigger mechanisms, or momentary switching functions.
