The Altra Pump Switch is used to turn a pump on and off in environments with temperatures up to 140° F. This product can be used for a variety of applications, including but not limited to: septic tanks, sump pits, holding tanks, pump chambers, water tanks, and any other liquid tanks. Available in 120/240VAC bare lead (no plug), 120VAC piggyback plug, and 240VAC piggyback plug, 13 or 15 Amp models.
The pump switches are mechanically operated using a microswitch and are activated by the ball inside the float housing. Available models include: A13 and A15 Series with narrow and wide angle switching differentials. For use as empty tank (normally open) or fill tank (normally closed) configuration with multiple types of float attachments for mounting and various cable lengths.
NOTE: Check to make sure the correct pump switch is being used for the application:
- Normally Open - Contacts are open while hanging down and will close on a rising liquid level. Typically used for empty tank applications.
- Normally Closed - Contacts are closed while hanging down and will open on a rising liquid level. Typically used for fill tank applications.
