Key Features
- SPST momentary OFF-(ON) action with 1.57 N actuation force for positive tactile feedback in control panels
- 24 VDC / 0.05 A rating suitable for low-power logic-level signaling in industrial and consumer electronics
- Polybutylene terephthalate (PBT) actuator material providing temperature resistance and long-term dimensional stability
- Through-hole PC pins for robust soldered PCB mounting with resistance to mechanical vibration
- Compact 10.16 × 7.11 mm body enabling dense switch arrays on space-constrained control boards
Applications
The 1-1825027-4 tactile switch is deployed in industrial control panels, medical device interfaces, and consumer electronics where a reliable momentary push input is required on a PCB. Its 24 VDC rating and PBT actuator make it a popular choice for test instruments, handheld terminals, and home appliance control boards that demand tactile confirmation with each press. Through-hole mounting ensures secure attachment in environments subject to vibration or repeated manual actuation cycles.

Frequently Asked Questions
What electrical rating does the 1-1825027-4 support, and is it compatible with 3.3 V microcontroller logic inputs?
The 1-1825027-4 is rated at 0.05 A and 24 VDC maximum, making it fully compatible with 3.3 V and 5 V microcontroller GPIO inputs when used with an appropriate pull-up resistor. Its low current rating is well matched to CMOS logic interfaces and optocoupler inputs, allowing direct connection to digital inputs on Arduino, STM32, and similar microcontroller boards without additional buffering.
How does the 1.57 N actuation force of the 1-1825027-4 compare to light-touch switches, and when should engineers choose a higher force rating?
The 1.57 N actuation force of the 1-1825027-4 provides a firm, deliberate click that reduces accidental triggering compared to ultra-light switches rated at 0.6–0.8 N. Designers select higher actuation forces in safety-critical panels—such as industrial emergency-stop adjacent controls—where inadvertent activation could cause equipment damage, while lighter forces below 1 N are preferred for compact handheld devices requiring rapid repeated keypresses.
Which PCB mounting approach does the 1-1825027-4 use, and how does through-hole mounting benefit high-vibration environments?
The 1-1825027-4 uses through-hole PC pins soldered directly into the PCB, providing a mechanical joint that withstands shear forces and vibration far better than surface-mount alternatives. In applications subjected to continuous vibration—such as vehicle dashboards or factory floor equipment—through-hole solder joints maintain electrical continuity under accelerations exceeding 10 g, whereas SMD pads may crack under repeated mechanical stress over a product lifetime of millions of actuations.
