Presair TVA111Z latching air switch

This Presair air switch allows you to switch on and off one of the pieces of equipment in your spa (pump, blower or light, for example). It is a "latching" switch: the contacter changes position once for each air impulse, and stays in position until the next one. It works with a air button and air switch tube. It has a center spout.

Pneumatic systems like this are now considered to be old fashioned (modern spas typically use low-voltage digital controls), but they are simple, inexpensive and easy to install.

This SPDT switch allows you to control a single piece of equipment, whereas you can control two pieces of equipment with a DPDT switch.
