ST-12 Bimetal Thermal Switch

Bimetal Thermal Switch

  • Snap Action
  • Automatic Reset
  • Superior Heat Response
  • Non-Phenolic Insulation

SEKI's bimetal thermal switch is used for preventing fire and damages caused by overheating in the circuit of electric & electronic products.

There are three models in our bimetal thermal switches, ST-12, ST-22 and CK. ST-12 is used for overheat protection for hair dryer, electric fan heaters, popcorn machines, electric ovens, dish dryers and etc. ST-22 and CK are used for overheat protection for electric motors, fluorescent ballasts, battery chargers, transformers, solenoids, heating pads, OA-machines and etc.

■ Thermal Cut-out

SEKI ST-12 bimetal thermal switch can be used for overheat protection of hairdryers electric fan heaters, popcorn machines, etc. SEKI's thermal cut-out is overheating protection device for electric appliances and they are reusable parts that are reset when equipment cools. If the fault still exists, the protectors continue to automatically protect the equipment.
