TBS-310

This switch is found at the back of the motor or sometimes in a plastic electrical box mounted near the motor.

It is what controls power being sent to the motor.

It is connected by air tubing to an air button that is mounted on the top side of the tub.

When you press on the air button, it sends a puff of air to the air switch to turn on the tub motor.

This type of control system ensures the tub user never comes in direct contact with electricity being in a wet environment.

If your tub is not coming on, make sure it is not the air button that has failed since there are no returns on electrical items.

There are many different manufactures that make this switch.

If there is a different part number on the switch you have, don't worry, they are all interchangeable.

This is a latching air switch.
