DSTH DIP Switch

DSTH DIP Switch: Robust Standard Profile and 2.54mm Pitch THT (through-hole technology) Switch

• 2.54mm standard pitch
• Robust THT design
• Extended actuator for easy switching
• Available in 3 colours: black, red, blue

The DSTH DIP Switch is a robust, standard-profile and 2.54 mm pitch THT (through-hole
technology) switch. It enables electronic devices to be configured directly at hardware level. Addresses, communication parameters, logic states and operating modes can be set easily and
clearly, without modifying software or firmware.

Electrically, the DSTH uses SPST contacts and offers 2~10, 12 multiply positions. Ratings are 25 mA at
24 V for frequently changing switching states and 100 mA at 50 V for constant switching states. Initial
contact resistance is ≤ 50 mΩ and ≤ 100 mΩ after the specified tests. Further specifications include a
dielectric strength of 500 V AC for one minute, 2,000 mechanical switching cycles and an operating force
of ≤ 8 N. The operating temperature range extends from -40 °C to +85 °C.

Typical applications include PLC controls, industrial servers, medical devices, robotics, air-conditioning
systems and household appliances. In these applications, the DSTH can be used for RS485 and
Modbus addressing, BIOS/CMOS settings, as well as the configuration of hardware parameters,
functions and operating modes. Combining proven performance, competitive cost and fast availability,
DSTH is an ideal solution for OEMs seeking a reliable alternative to premium-priced standard DIP switch
brands.

AFDD Arc Fault Detection Device

Eaton’s AFDD provides comprehensive protection against
electrical fires triggered by arc faults. This all-in-one
device combines the functions of a residual-current
circuit breaker, miniature circuit breaker, and arc fault
detection, protecting against electric shock, overcurrent,
short circuits, and arc faults. Through continuous electronic
cable monitoring, the device detects arc faults and trips
automatically to reduce the risk of residential electrical
fires. It provides electricians with a more efficient,
standards-compliant solution for enhanced safety.

Core Features:

• Advanced protection: combines arc‑fault detection, overcurrent & short‑circuit protection and earth‑fault (RCCB) functionality.
• Rated breaking capacity 6 kA and 10 kA
• Rated currents up to 40 A
• Tripping characteristics B, C
• Tripping indicators show status and trip cause, saving fault‑finding time
• AFDD busbar as accessory supports easy and flexible installation

Single Module AFDD
Eaton’s single-module AFDD range delivers all-in-one protection in a compact design. Engineered for residential and commercial applications, it enables space-saving distribution boards and seamless upgrades of existing installations, while supporting compliance with BS 7671 AFDD requirements.

Features:

• Arc fault, overload, short circuit & residual current protection
• Only 18 mm width
• 6 & 10kA
• 6 - 40A
• B & C Characteristic
• Type A
• Idn 30mA

Types

• Type -A: Protects against AC and pulsating DC residual currents.
• Type -Li/A: As Type -A, but in addition it is short-time delayed. Highly reliable against unwanted tripping.
• Type -G/A: 10 ms time delay in order to avoid unwanted nuisance tripping (e.g. during thunderstorms).
• Type -F: Higher immunity against smooth DC currents and enhanced surge current proof capabilities.
