Classification and switching structure of slide switches

Common types of slide switches include single-pole double-position, single-pole triple-position, double-pole double-position, and double-pole triple-position. They are generally used in low-voltage circuits and feature flexible slider action and stable, reliable performance. Slide switches are widely used in various instruments/meters, electric toys, fax machines, audio equipment, medical equipment, beauty equipment, and other electronic products.

Slide Switch Classification

Multi-function switches are divided into: low-current toggle switches and high-current slide switches. Low-current slide switches are commonly used in electronic toys and digital communications. High-current toggle switches are generally used in electrical appliances, machinery, etc. High-current toggle switches specifications and electrical performance: Rated power: DC 50V 0.3A; Operating temperature range: -20℃～60℃. Slide switch performance in various aspects:

I. Electrical performance specifications

1. Contact resistance test: Tested under low current (100mA). Requirement: Less than 30 milliohms.

2. Insulation resistance test: Input 500V DC voltage for 1 minute, and test according to the following contact method:

(1) Between contact terminals.

(2) Between the rubber base and the pins. Requirement: 100 megohms or higher.

3. Withstand Voltage Test: Input AC 500V (50-60Hz) voltage, sensitivity current 0.5mA for 1 minute, test according to the following contact methods:

(1) Between the pins themselves.

(2) Between the pins and the casing. Requirement: No insulation damage or other abnormalities.

Slide Switch

A slide switch is mainly assembled from the following components through appropriate processing:

1. Iron Shell (Material: generally iron; Processing: nickel plating or blackening to prevent oxidation)

2. Plastic Handle (Material: generally POM; PA nylon is often used if flame retardancy and high temperature resistance are required; Processing: injection molding)

3. Terminal Block (Material: generally phosphor bronze; Processing: silver plating)

4. Insulating Base Plate (Material: bakelite; Processing: stamping)

5. Contact Chip (Material: generally phosphor bronze; Processing: silver plating)
