The Metal Push Button Switch symbol is commonly used on circuit diagrams and device identification to facilitate identification and operation. Here are some common metal push button switch symbols:
1. **Normally open (NO) switch**:
- The symbol is usually represented as an open circle with a line next to it, indicating that the circuit is open when not pressed and closed when pressed.
2. **Normally closed (NC) switch**:
- The symbol is usually represented as a closed circle with a line next to it, indicating that the circuit is closed when not pressed and open when pressed.
3. **Self-reset switch**:
-The symbol is similar to a normally open switch and is usually labeled “Momentary” or “Push Button”.
4. **Self-locking switch**:
The – symbol is usually represented as a circle with an arrow, indicating that the state remains when pressed and does not change when released.
5. **Lighted switch**:
- The symbol may have a small lightbulb symbol added next to the switch symbol to indicate that the switch has a pilot light.
These symbols are used in circuit diagrams to help the user quickly identify the type and function of a switch. When designing a circuit or device, be sure to use the correct symbols to avoid confusion.
