Secoh JDK & TKO Series Auto-Stopper (Safety Switch)

Genuine Secoh Replacement Auto-Stopper (Safety Switch) - JDK & TKO Series

Ensure your Secoh air pump stays protected with a genuine replacement Auto-Stopper (Safety Switch) Assembly. The built-in mechanical safety switch is one of the most vital protective features inside Secoh linear air pumps, designed to immediately cut power to the electromagnet in the event of a diaphragm tear or failure.

By shutting off power instantly when an internal fault occurs, the safety switch prevents the central magnet from striking internal housings, saving your motor core and internal valve structures from severe damage. Whether you are replacing a worn micro-switch mechanism during a major overhaul or restoring a tripped pump, using a genuine Secoh safety switch guarantees accurate trigger sensitivity and total peace of mind.

Key Features & Benefits:

• Genuine Secoh OEM Component: Factory-engineered to match exact electrical and mechanical specs for Secoh JDK and TKO series blowers.

• Instant Motor Protection: Immediately trips and cuts electrical power if a diaphragm ruptures, preventing catastrophic internal motor damage.

• Resettable Design: Features a mechanical sliding toggle mechanism that can easily be reset after installing a new Chamber Block / Diaphragm Kit.

• Durable Electrical Contacts: Built to handle continuous electrical load and harsh, damp septic tank environments without corrosion or premature failure.

• Direct-Fit Replacement: Designed for straightforward installation on the main internal chassis frame.

Replacement / Inspection Recommendations:

• After a Diaphragm Failure: If a diaphragm tears and the safety switch trips, inspect the slider and contacts for mechanical wear or electrical burning before resetting.

• Pump Fails to Power On: If your power supply is active but the pump remains completely silent after resetting the switch, the internal safety switch assembly or micro-switch contacts may need replacement.

• During Major Pump Overhauls: Recommended to replace when rebuilding older pumps that have seen many years of continuous duty.
