The Jabsco 2090770 is a genuine Jabsco replacement switch for Jabsco pumps that list this part. The switch controls when the pump motor runs, so when it fails the pump may not start, may run continuously, or may turn on and off erratically.
Replacing a faulty switch with the correct genuine part restores normal automatic operation and protects the motor from running when it should not. Before ordering, confirm the pump model from its label and check the wiring and fuse, since a blown fuse or loose connection can look like a failed switch.

Frequently Asked Questions
Q: How do I know the switch is the problem?
If the pump has power at its terminals but will not run, or will not stop when it should, the switch is a likely cause. Check the fuse and wiring first.
Q: Is it safe to replace the switch myself?
Yes, with power disconnected at the breaker or battery. Note the wire positions before removing the old switch.
Q: What else can cause erratic pump cycling?
Leaking check valves, a small leak in the plumbing, or air in the system can all make a pump cycle, even with a good switch.
Q: How do I confirm this switch fits my pump?
Match the pump model number from its label to the parts list, or send us a photo of the pump plate and we will confirm it.
