Alderon's Altra™ Control Switch is used for the activation of alarms and control circuits in environments with temperatures up to 140° F. This product can be used for a variety of applications, including but not limited to: high or low water alarm panels or low amperage pump control circuits under 5 amps. Available in 120/240VAC bare lead models.
To provide a pivot point, these control switches are supplied with a stainless steel clamp to secure the float switch cable to the pump discharge pipe. Alternatively, an optional cable weight is available.
NOTE: Check to make sure the correct control 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 high level alarms and tank emptying applications.
- Normally Closed - Contacts are closed while hanging down and will open on a rising liquid level. Typically used for low level alarms and tank fill applications.
Floats can be wired to be either normally open (high level), or normally closed (low level) depending on your application.
