Temperature Switches - Ashcroft
Temperature switches open or close a contact at a set temperature to start fans, stop heaters, trigger alarms or shut down equipment. They're simple, dependable temperature protection.
Switch Types
- Mechanical switches – bulb and capillary or bimetal
- Electronic switches – adjustable set points and displays
- Limit switches – high-limit safety shutoff
- Explosion-proof switches – hazardous areas
Choosing a Switch
Select range, deadband, contact rating and sensor style. Use thermowells for pressurized systems. Manual-reset limits add safety.
Centro supplies temperature switches for equipment protection and control.
