MQ165 3Interlock 1Reset 1Latching 5 Keys Switch 250VAC 4A for Kitchen Hood The MQ165 is a 5 keys switch designed for kitchen hood control applications. It combines three interlock actions with a reset and a latch function, delivering a safe and deliberate operation in common commercial kitchen environments. Rated for 250 VAC and 4 A, this switch provides a compact, panel mounted solution for controlled ventilation and safety interlock needs. Key benefits Enhanced safety through 3 interlocks that require specific conditions to be met before operation, reducing the risk of accidental starts. Deliberate restart and control with a dedicated reset function that clears the latch and reenables operation only after a deliberate action. Security and control flexibility with a 5 keys configuration, enabling multistep or authorized operation within the hood control system. Reliable, purposebuilt design for kitchen hood installations, suitable for daily use in commercial environments. Compact form factor and straightforward integration into standard control panels, supporting clean and organized panel layouts. Key attributes Model: MQ165 Type: 5 Keys Switch with 3 Interlock, 1 Reset, 1 Latching Electrical rating: 250 VAC, 4 A Application: Suitable for kitchen hood control panels and related ventilation systems Functionality: 3 interlock actions, 1 reset, 1 latch Keys: 5 keys incorporated into the switch mechanism Compatibility: Intended for control circuits in kitchen hood installations and similar 250 VAC control environments Size and material: not specified in the available information; described as a compact switch suitable for panel mounting Performance: designed to provide secure interlock operation, deliberate latching behavior, and reliable reset capability in a 250 VAC, 4 A circuit Functionality overview Interlock: The three interlock features create a controlled sequence or mutual exclusion that prevents unintended activation. Reset: A dedicated reset function allows the operator to clear fault or trip conditions and reenable operation after confirmation. Latching: The latch maintains the switch state until a reset action or an explicit state change is performed. Keys: The five keys configuration enables multiple control steps or authorization options within the hood control system. Compatibility and use cases Use in commercial kitchen hood control panels where a secure, multistep activation sequence is desired. Suitable for hood fan control circuits that require interlocks to prevent startup during maintenance or when safety doors are open. Applicable in environments where a deliberate, authorized restart is needed after a fault or service, ensuring that operation resumes only after appropriate action. Use cases Primary ventilation control: Integrate the MQ165 into a kitchen hood panel to manage fan operation with interlock protection and a reset requirement, ensuring safe startup during daily operations. Maintenance and service mode: Employ the reset function to safely reengage the hood after servicing, with the latch state preserved until reset is performed. Securityconscious operation: Implement a fivekey control scheme to restrict activation to authorized personnel in busy commercial kitchens, reducing the risk of unintended use. Notes for selecting and installing Confirm that the control circuit wiring and switching requirements match the 250 VAC, 4 A rating. Plan the panel layout to accommodate the 5key arrangement and ensure clear labeling for safe operation. If material specifics are required for enclosure or mounting compatibility, consult the product supplier for detailed specifications. This description presents the MQ165 as specified: a 3interlock, 1reset, 1latching, 5keys switch rated 250 VAC and 4 A, designed for kitchen hood applications, with emphasis on safety, controlled operation, and practical use in professional kitchens.
