The push,turn on control has become very difficult to push on and off what can i do?

Disconnect power from the system. 2. Purchase a can of www.ultra-lube.com (This type f lubricant will not cause breakdown of rubber, silicone or plastic seals) multi purpose lube. HomeDepot sells it. Black green and silver spray can. 3. Remove the knob using the right size Allen wrench. 4. Spray lube into the neck of the actuator. 5. Wipe off any lube from the knob shaft. 6. Re install the knob and push pull a few times to distribute the lubricant. 7. Restore power and test system.

If this does not solve the problem then there may be a mechanical failure in progress. Go online at the manufactures website to order a new switch.
