[Industrial Control Products] How does the Reset Type Limit Switch Achieve its Function

Recently, we have received a lot of inquiries about the T4N series safety limit switches.

The most frequently asked question is what this reset is for. Can you demonstrate it to us? Actually, it starts from the principle of the safety limit switch.

The normally closed contact NC of most TMAZTZ safety limit switches has the function of forced disconnection, and when fusion occurs, the circuit is cut off by depressing the NC contact with the plunger. However, in some cases, the operator needs to remove all faults before resetting the device. This is where our T4N-R series with a blue handle comes into play. It has an additional manual reset mechanism between the switch operating head and the body. All other structures are identical to the T4N-▢ series.

For most of the T4N series limit, switches have their corresponding reset models, but there are a few switches that cannot be retrofitted because of the mechanism. Do you know which ones they are?
