what is the specification of the metal push button switch

The specification for a metal pushbutton switch can vary depending on the application and manufacturer. However, typical specifications to consider include:

Electrical Specifications

1. Rated Voltage: The maximum voltage the switch can handle (e.g., 12V, 24V, 120V, 240V).

2. Rated Current: The maximum current the switch can handle (e.g., 1A, 3A, 5A).

3. Contact Resistance: The resistance across the contacts when the switch is closed, usually measured in milliohms (mΩ).

4. Insulation Resistance: The resistance between the contacts when the switch is open, typically measured in megaohms (MΩ).

5. Dielectric Strength: The maximum voltage the switch can withstand between the contacts and the case without breaking down, usually specified in volts (V).

Mechanical Specifications

1. Button Actuation Force: The force required to press the button, measured in grams-force (gf) or newtons (N).

2. Travel Distance: The distance the button moves when pressed, measured in millimeters (mm).

3. Switch Life: The number of times the switch can be operated (pressed and released) before failure, often specified in thousands or millions of cycles.

4. Mounting Type: Panel mount, PCB mount, or surface mount, with details on mounting hole size and thread type.

Environmental Specifications

1. Operating Temperature Range: The range of ambient temperatures the switch can operate in, typically specified in degrees Celsius (°C).

2. Storage Temperature Range: The range of temperatures the switch can be stored in without damage.

3. Ingress Protection (IP) Rating: Indicates the level of protection against dust and water (e.g., IP65, IP67).

4. Vibration and Shock Resistance: The switch's ability to withstand mechanical vibrations and shocks, usually specified in Gs or m/s².

Physical Specifications

1. Dimensions: The size of the switch, including diameter, height, and panel cutout dimensions.

2. Material: The materials used for the button cap, housing, and contacts (e.g., stainless steel, brass, gold-plated contacts).

3. LED Indicator: If the switch has an integrated LED, specifications for the LED, such as color, voltage, and current.
