The PP1 and PP2 series push-pull switches from Lamb Industries, Inc. (Portland, OR) have push-and-pull capable actuators and can be specified for the unique ON2-ON1-(ON2) function. This function is a standard crossover function with an option of either a momentary action when the actuator is pushed or a maintained action when the actuator is pulled.
The switches are UL approved for 16 A at 125 VAC, 12 A at 250 VAC, and 1 hp at 125/250VAC. The PP1 is designed to snap into a panel with a 13.2 × 28-mm mounting hole, while the PP2 snaps into a 13.5 × 36-mm mounting hole. Both versions have several different standard terminal sizes and actuator shapes.
