Slide Switches

1. Overview

Slide switches are electromechanical devices that control electrical circuits through linear sliding motion. They serve as fundamental components in electronic systems for power control, signal routing, and mode selection. Their compact design and reliable performance make them essential in modern electronics, from consumer devices to industrial machinery.

2. Major Types and Functional Classification

Type	Functional Characteristics	Application Examples
Single-Pole Single-Throw (SPST)	Simple on/off control	Power switches in portable devices
Single-Pole Double-Throw (SPDT)	Three-terminal switch for circuit selection	Mode selection in measurement instruments
Double-Pole Double-Throw (DPDT)	Simultaneous control of two circuits	Motor direction control in robotics
Miniature Slide Switches	Sub-10mm housing for space-constrained designs	Smartphone SIM card trays
Heavy-Duty Slide Switches	High current/voltage ratings	Industrial machinery control panels

3. Structure and Components

Typical slide switches consist of: - Insulating housing (thermoplastic/phenolic resin) - Conductive contacts (phosphor bronze or beryllium copper) - Gold-plated terminals for corrosion resistance - Sliding actuator with detent mechanism - Sealing membranes for environmental protection (IP67 rated models)

4. Key Technical Specifications

Parameter	Typical Range	Importance
Rated Current	0.1A - 10A	Determines load capacity
Operating Voltage	3V - 250V	Defines circuit compatibility
Contact Resistance	10m - 100m	Affects power efficiency
Dielectric Strength	500V - 2kV	Safety insulation measure
Mechanical Life	5,000 - 50,000 cycles	Device longevity indicator

5. Application Fields

Consumer Electronics: Smartphones, tablets, gaming consoles
Industrial Equipment: CNC machine controls, PLC systems
Automotive Systems: HVAC controls, infotainment interfaces
Medical Devices: Diagnostic equipment, patient monitors
Aerospace: Avionics control panels, navigation systems

6. Leading Manufacturers and Products

Manufacturer	Representative Product	Key Features
C&K Components	PTS645 Series	IP67 sealed, 10A rating
Eaton	EH063 Series	High-vibration resistance for automotive
Omron	SS-4 Series	PCB mount with 0.5mm contact gap
