Specifications:
The PH Subminiature Pushbutton Switch is designed with various specifications to ensure reliability and performance. It features an insulation resistance of more than 100MΩ at 500VDC and a dielectric strength of 1000V AC between terminals and 1500V AC between terminal and ground. The contact resistance is less than 30mΩ initially at 1A 6VDC and less than 50mΩ at 0.1A 6VDC. The switch is rated for 0.1A 125VAC, 0.1A 30VDC for resistive loads, and 5A 125, 250VAC for resistive loads.

Mechanical and Electrical Life:
The switch offers a mechanical life of 300,000 operations for momentary and 200,000 operations for alternate types. The electrical life is rated at 50,000 operations minimum at rated load and 100,000 operations minimum at rated load.

Environmental Conditions:
The switch operates effectively within an ambient temperature range of -15°C to 50°C and up to 80% relative humidity.

Features:
The switch is available in small types with nut fixing and snap-in types. It comes in various button sizes: 12mm square, 12x17.2mm rectangular, and 10mm round. The contacts are made of silver, gold-plated silver, and W/E alloy cross-bar.
