Horizontal Push Switch

A horizontal push switch is a mechanical switch that uses horizontal (usually transverse) force to turn on and off a circuit. Its core structure consists of a contact system (including dynamic and static contacts), a drive mechanism (push rod, spring), a housing protection (IP level design), and electrical interfaces (solder pins/terminals). The working principle is based on mechanical displacement triggering contact closure or disconnection, with the characteristics of rapid response and compact structure, commonly used in industrial control, consumer electronics, and automotive electronics fields.

characteristic

Operating force and stroke

Typical operating force range: 1.5N~5N (± 10% error), ensuring user comfort during operation.

Horizontal stroke: 2.0mm~4.5mm. Short stroke design (such as 2.0mm) is suitable for high-frequency operation scenarios, while long stroke (such as 4.5mm) can reduce the risk of accidental contact.

Example: A certain industrial grade switch adopts 3N operating force+3.0mm stroke, balancing hand feel and reliability.

Electrical performance

Rated current: 0.1A~20A (@ 250V AC/DC), high current models (such as 20A) require silver alloy contacts to reduce temperature rise.

Insulation resistance: ≥ 100M Ω (@ 500V DC), ensuring long-term safety during use.

Contact resistance: ≤ 50m Ω (initial value), low resistance design reduces energy loss.

Voltage endurance: AC1500V/1 minute (base insulation test), meeting the high voltage isolation requirements of industrial equipment.

mechanical life

Typical lifespan: 50000 to 1 million cycles (full stroke operation), high-end models achieve ultra long lifespan through gold-plated contacts and self-cleaning structure.

Example: After 1 million tests, the contact resistance change rate of a switch used in a medical device is less than 15%.

Environmental adaptability

Working temperature: -40 ℃~+85 ℃ (some models support -55 ℃~+125 ℃), meeting extreme environmental requirements.

Protection level: IP67 (dustproof and waterproof) to IP69K (high-pressure water flushing), suitable for outdoor or high humidity environments.

Impact resistance: 50G (11ms half sine wave), compliant with MIL-STD-202F standard.

Dimensions and installation

Common packaging: 6mm × 6mm~22mm × 22mm (patch/plug-in), supporting reflow soldering or wave soldering processes.

Installation method: Panel installation (with nuts) or PCB direct insertion, highly flexible.

Typical application scenarios

Industrial Automation

Used for PLC input modules and emergency stop buttons, it must meet UL/CSA certification and IP65 protection.

Example: A certain food packaging machine adopts an IP67 horizontal push switch, which is oil resistant and has a lifespan of 500000 times.

Consumer Electronics

Smartphone volume keys and smartwatch function keys require ultra-thin design (≤ 3mm height) and long trigger stroke (≥ 3.5mm) to enhance tactile experience.

Example: The side keys of a flagship phone use gold-plated contacts and a 2N operating force, and have passed 100000 button tests.

Automotive Electronics

The car air conditioning control panel and seat adjustment switch need to pass AEC-Q200 certification, with a working temperature of -40 ℃~+125 ℃.

Example: The central control switch of a new energy vehicle adopts an IP69K design and supports high-pressure water gun cleaning.

medical equipment

The operation panel of ventilators and monitors requires low contact resistance (≤ 20m Ω) and high insulation performance (≥ 1G Ω).

Example: A portable defibrillator switch has passed biocompatibility testing (ISO 10993-5) to ensure non toxicity.
