Multicomp Pro MCDHA-08TQR 8-Way Slide DIP Switch, SMD, 24V DC

The Multicomp Pro MCDHA-08TQR is a top tape sealed, half-pitch DIP switch designed for reliable circuit configuration in compact electronic assemblies. This surface-mount device (SMD) offers a low-profile design with a height of just 2.2mm, making it ideal for space-constrained applications. It features eight individual SPST (Single Pole, Single Throw) switches, allowing for flexible binary address or function selection.

Constructed with high-reliability gold contacts, the switch ensures excellent electrical conductivity and long-term stability, with a maximum initial contact resistance of 100mΩ. It is rated for a switching capacity of 25mA at 24V DC and features flush mounting for a clean, integrated appearance on printed circuit boards (PCBs). The operating temperature range of -40°C to 85°C guarantees dependable performance in harsh industrial environments.

Key Features & Benefits

• Compact Half-Pitch Design: Saves valuable PCB real estate compared to standard DIP switches.
• Surface Mount Technology (SMD): Enables automated assembly processes for high-volume production.
• High Reliability: Gold-plated contacts minimise oxidation and ensure stable, low-resistance connections over the product's lifecycle.
• Robust Construction: Sealed tape design helps protect against contamination during soldering and in the operating environment.
• Clear Actuation: The slide actuator requires an operating force of 500gf, providing positive tactile feedback for each setting.

With an insulation resistance of at least 100MΩ at 500V DC and a mechanical life of 1,000 cycles, this DIP switch is a durable and trustworthy component for setting critical parameters. It is a fundamental part for configuring devices in industrial control, power management systems, and automation equipment where manual, non-volatile setting changes are required.
