1.Relais 1.Relais is a general-purpose electro-mechanical relay designed to switch a load under control of a separate signal. It provides electrical isolation between control and load circuits and delivers reliable operation in a compact package. The enclosure and terminals support easy mounting in standard enclosures or on PCBs, and the device uses durable materials for long service life. Key benefits - Enables safe isolation between control electronics and powered loads - Simple integration with common controllers and drivers - Flexible contact configurations to cover typical switching needs - Small footprint suitable for tight spaces - Robust construction for repeated cycling and steady performance Core attributes - Function: switches a load under control of a signal - Compatibility: available with multiple coil voltages and contact forms to match different systems (for example normally open and normally closed configurations) - Size: compact body designed for space-constrained installations - Material: epoxy encapsulation, copper alloy contacts, and a molded plastic housing - Performance: reliable switching with durable contacts and insulation for repeated use in hobbyist and light-industrial applications Use scenarios - Control a lighting or indicator circuit from a microcontroller or PLC while keeping control electronics isolated from the power side - Drive a small motor, valve, or actuator in a home automation or laboratory setup through a safe, isolated interface - Interface sensors or alarms to higher-power equipment, enabling safe, programmable control without direct power routing through the control circuitry
