The telescoping end of plunger can be compared to a car shock absorbers as only part of the motion is passed to the switching element.

 

**These are the components:**

- Plunger Body
- Plunger Guide
- Telescoping Spring
- Return Spring
- Guide Cage
- Plunger Pin

By this technique is a soft actuate the switching element. The telescoping ends plunger may not be used for safety applications, as to be guaranteed by the telescopic spring force to a safe opening is insufficient (bonded contacts will not be opened).

 

**Rigid Plunger:**

Each movement of the plunger body is passed directly to the switching element. Plunger and switching pin form a unit. The spring pushes the plunger back to the starting position.

 

**These are the components:**

- Plunger Body
- Plunger Guide
- Return Springs
- Guide Cage
- Plunger Pin

 

The plunger body and switch pin assembly make this plunger type acceptable for safety applications. Since the element is opened by the actuation of the plunger (possibly destroyed).
