The OTTO P5-V switch offers the functionality of the P5 alternate action switch with the added benefit of an aluminum security level case and button or a stainless steel vandal proof case and button. Push and the P5-V series switch holds “on”; push again and the switch turns “off.” Positive tactile feedback is featured so the operator is aware the switch mode has been executed. The button returns to the original position after each actuation. The P5-V series is sealed at the button with a patented rolling sleeve design.
